The dreaded “check engine” light…

checkengine

Since we’ve gotten the truck, a little over a year ago, the “check engine” light has been on and off constantly.  The DEF (diesel exhaust fluid) light has been an issue also, but we finally got that fixed when there was a recall about a month ago in Louisiana.  We drove up to Ohio with no obnoxious warning lights and then the other day… BAM! Here’s the “check engine”.  I stopped at Advance Auto Parts yesterday to have them test it and it came across as code: P0677. Which is the cylinder 7 circuit, that has to do something with a glow plug. From my understanding, diesels have glow plugs instead of spark plugs.  And since we have 8 cylinders, we have 8 glow plugs.  I watched a video on YouTube about how to change these little guys, but it looks a bit too out of our non-mechanical league to attempt ourselves.  So I’m waiting on a call from the Duramax diesel expert in Xenia, Ohio so he can fix it.  Fingers crossed that’s all it is!

UPDATE:  After a half hour drive through scenic Xenia, I arrived at the shop.  Josh at Fisher’s Shop replaced glow plug number 7 and I was on my way… Lucky us!
